damp/moldy smell coming from vents....
Anyone know the cause?
I'd try bullet #1 before shooting any solution into the AC vents first however.

It might take a couple of cans the of evaporate flush / cleaner to rid the odor
but the flush will clean out the evaporate case and any mold
To help control the odor you can try turning the a/c off before shutting the car off.that will help control the water in the a/c evaporate case
